Abstract (en)
[origin: EP1048972A2] A liquid crystal display element of the present invention comprises a pair of substrates 1, 2 with transparent electrodes 5, 6, a spacer 3 for maintaining a certain gap between the substrates, which is disposed between the pair of substrates 1, 2, and a liquid crystal layer 4 sealed between the substrates 1, 2; in which the spacer 3 has an elasticity, the sum of a repulsion force of the spacer 3 and an internal pressure of the above-mentioned liquid crystal layer 4 is constantly approximately 1 atm with a change in temperature within a range of usable temperatures of the liquid crystal display element, and each of the spacer 3 and the internal pressure of the liquid crystal layer 4 varies linearly. According to such a constitution, it is possible to improve a temperature characteristic of the grade of display resulting from a firm column-shaped spacer with little elasticity, and to realize a liquid crystal display element with little deterioration in the grade of display due to a change in temperature. <IMAGE>
